docs: add note about non-deterministic sort order in collections

[davidumoru]

Description (required)

Added a note to the “Querying Collections” section of the Content Collections guide, explaining that the order of entries returned by getCollection() is non-deterministic and platform-dependent. This helps users understand that they should sort the results themselves if they need a specific order.

Related issues & labels (optional)

• Closes Explain that output order is not reliable when using getCollection #11674
• Suggested label: improve or update documentation

Hi @davidumoru! I was sure we had already written about this! Turns out, it's in the Upgrade to v5/from legacy collections guidance, but not here on this page. 😅

Thank you for adding this helpful information in a place where more people will find it, and you'll find my suggestions below for making it fit within the flow of this new location!

[davidumoru]

Thanks for the suggestions, just committed them. This version reads much better.
